Method Detail

tag

Tag tag()

Returns:

The tag

usePrimitive

void usePrimitive(boolean isPrimitive)

Use primitive or constructed.

isPrimitive

boolean isPrimitive()

Tells if it is PRIMITIVE or not.

Returns:

true if using PRIMITIVE, false otherwise

useDefinitiveLength

void useDefinitiveLength(boolean isDefinitiveLength)

Use definitive length or not. Note definitive length only makes sense when it's constructed.

isDefinitiveLength

boolean isDefinitiveLength()

Tells if it's definitive length or not.

Returns:

The boolean value

useImplicit

void useImplicit(boolean isImplicit)

Use implicit or not.

isImplicit

boolean isImplicit()

Tells if it's is IMPLICIT or not.

Returns:

true if using IMPLICIT, false otherwise

useDER

void useDER()

Set encoding type as DER.

isDER

boolean isDER()

Tells if it's is DER

Returns:

true if using DER, false otherwise

useBER

void useBER()

Set encoding type as BER.

isBER

boolean isBER()

Tells if it's is BER

Returns:

true if using BER, false otherwise

useCER

void useCER()

Set encoding type as CER.

isCER

boolean isCER()

Tells if it's is CER

Returns:

true if using CER, false otherwise

encodingLength

int encodingLength()
            throws IOException
